Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565302, here are decompositions:

3 + 31565299 = 31565302
5 + 31565297 = 31565302
11 + 31565291 = 31565302
23 + 31565279 = 31565302
53 + 31565249 = 31565302
71 + 31565231 = 31565302
173 + 31565129 = 31565302
233 + 31565069 = 31565302

Showing the first eight; more decompositions exist.
